How would you describe the sea state under Code 9?
How would you describe the sea state under Code 9?
The sea state can either be assessed by an experienced observer, like a trained mariner, or through instruments like weather buoys, wave radar or remote sensing satellites….WMO sea state code.
| WMO Sea State Code | Wave height | Characteristics |
|---|---|---|
| 8 | 9 to 14 metres (30 to 46 ft) | Very high |
| 9 | Over 14 metres (46 ft) | Phenomenal |
What is a phenomenal sea?
A Phenomenal sea is classified as having a significant wave height of 14.0m or more and this was recorded at both M6 and M3 buoys. The depression responsible for these waves was an Ex-Hurricane named EPSILON, which originally developed off Bermuda before being ‘consumed’ into the Jetstream.
How many sea states are there?
The United States has a total of 30 coastal states with over 12,000 miles of ocean coastline. There are five different coasts of the United States: the Atlantic Coast (East Coast), the Pacific Coast (West Coast), the Gulf Coast, the Arctic Coast, and lake states.
What does moderate sea state mean?
1.25 to 2.5m Moderate. 2.5 to 4m Rough. 4 to 6m Very Rough. 6 to 9m High. 9 to 14m Very High.
Are 2m waves big?
A measure that many surfers also use is the classic one: small waves (up to 1 meter), half a meter (up to 1.5 meters), meter (up to 2 meters high), last meter (over 2 meters high), meter and a half (over 2.5 meters), while those starting from 2 meters are considered big waves.
What are calm seas?
If the sea or a lake is calm, the water is not moving very much and there are no big waves.
How do you read sea state?
Just as the wind on your face can tell you if the wind has veered, sea state can tell you what is happening on the surface of the water….Swell.
| Degrees | Description |
|---|---|
| 1 | Very Low (short or average and low wave) |
| 2 | Low (long and low wave) |
| 3 | Light (short and moderate wave) |
| 4 | Moderate (average and moderate wave) |
What state has the longest coastline?
Alaska
Table
| State or territory | Method 1 (CRS) | Method 2 (NOAA) |

| Alaska | 6,640 mi (10,690 km) | 1 |
| Florida | 1,350 mi (2,170 km) | 2 |

What is a comfortable wave period?
Posts: 44,090. Images: 241. Re: Wave height / Period /Wind speed comfort. I’ve always felt that a wave period (in seconds) of 1.33 times the wave height (in feet) generally provides a comfortable ride. A wave period equal to, or less than, wave height (square waves) will be very uncomfortable.
Can you surf 1 ft waves?
Most surfers will call an average height rather than basing a session on rogue set waves/ the biggest of the day. As a general rule, if it’s only 1ft, it’s pretty difficult to surf on, unless you longboard or are a lightweight grom/ shredding machine!
